The wiring should be done by a qualified electrician A qualified electrician needs to knows the following before wiring: 1. The amperage rating of the electrical box should be adequate. Refer to the Specification Chart, in the parts manual, for this information. 2. The supply line should have the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on side of motor, for this information. NOTE: The wiring must be the same as the motor nameplate voltage plus or minus 10%. Refer to local codes for recommended wire sizes, correct wire size, and maximum wire run; undersize wire causes high amp draw and overheating to the motor. Risk of Electrical Shock. Electrical wiring must be located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders. GROUNDING INSTRUCTIONS This product should be connected to a metallic, permanent wiring system, of an equipment-grounding terminal or lead on the product. Voltage and Circuit Protection Refer to the specification chart for the voltage and minimum branch circuit requirements. 11-ENG D27042 Air Distribution System Risk of Bursting. Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst from air pressure. Use only metal pipe for air distribution lines. The next figure represents a typical air distribution system. The following are tips to remember when setting up the air compressor’s air distribution system. ● Use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air. AIR FLOW ● If piping is over 100 feet long, use the next larger size. ● Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks. ● A flexible coupling is recommended to be installed between the air discharge outlet and main air distribution line to allow for vibration. ● A separate regulator is recommended to control the air pressure. Air pressure from the tank is usually to high for individual air driven tools. FEEDER LINES SLOPE WITH AIR FLOW MAIN DISTRIBUTION AIR LINES Slope pipe in direction of air flow. Water condensate flows along bottom of pipe to drain legs, preventing it from entering feeder lines.

Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference. Pressure Switch On/Auto/Off Switch Tank Pressure Gauge Safety Valve Globe Valve Description of Operation Become familiar with these controls before operating the unit. On/Auto/Off Lever: Turn this switch "On/Auto" to provide automatic power to the pressure switch and "Off" to remove power at the end of each use. Pressure Switch: The pressure switch automatically starts the motor when the air tank pressure drops below the factory set "cut-in" pressure. It stops the motor when the air tank pressure reaches the factory set "cut-out" pressure. Safety Valve: If the pressure switch does not shut off the air compressor at its "cut-out" pressure setting, the safety valve will protect against high pressure by "popping out" at its factory set pressure (slightly higher than the pressure switch "cut-out" setting). Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank. Globe Valve (sold separately): Opens and closes air discharge valve. Turn knob counter-clockwise to open and clockwise to close. Regulator (sold separately, not shown): An air pressure regulator or a separate air transformer which combines the functions of air regulation and/or moisture and dirt removal is recommended for most applications. Cooling System (not shown): This compressor contains an advanced design cooling system. At the heart of this cooling system is an engineered fan. It is perfectly normal for this fan to blow air through the vent holes in large amounts. You know that the cooling system is working when air is being expelled. 13-ENG D27042 Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet. Drain Valve: The drain valve is located at the Drain base of the air Valve tank and is used to drain condensation at the end of each use. Check Valve: When the air compressor is operating, the check valve is "open", allowing compressed air to enter the air tank. When the air compressor reaches "cut-out" pressure, the check valve "closes", allowing air pressure to remain inside the air tank. 2. Allow the motor to cool. 3. Depress the red reset button on the motor. 4. Place the On/Auto/Off lever in the "On/Auto" postion to restart the motor. Reset Button Air Intake Filter (not shown): This filter is designed to clean air coming into the pump. This filter must always be clean and ventilation openings free from obstructions. See "Maintenance". Check Valve Pressure Release Valve: The pressure release valve located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches "cut-out" pressure or is shut off. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this valve for a few seconds. No air should be heard leaking when the motor is running or after the unit reaches "cut-out" pressure. Pressure Release Valve D27042 Motor Overload Protector: This motor has a manual thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart: 1. Place the On/Auto/Off lever in the "Off" position. How to Use Your Unit How to Stop: 1. Set the On/Auto/Off lever to "Off". Before Starting Break-in Procedure Risk of Unsafe Operation. Serious damage may result if the following break-in instructions are not closely followed. This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced. 1. Make sure the On/Auto/Off lever is in the "Off" position. 14-ENG 2. 3. 4. 5. 6. 7. 8. 9. Check oil level in pump. See "Oil" paragraph in the "Maintenance" section for instructions. Recheck all wiring. Make sure wires are secure at all terminals connections. Make sure all contacts move freely and are not obstructed. Open the globe valve fully to permit air to escape and prevent air pressure build up in the air tank during the break-in period. Move the On/Auto/Off lever to "On/Auto" position. The compressor will start. Run the compressor for 20 minutes. Make sure the globe valve is open and there is minimal air pressure build-up in tank. Check all air line fittings and connections/piping for air leaks by applying a soap solution. Correct if necessary. NOTE: Minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance. Check for excessive vibration. Readjust or shim air compressor feet, if necessary. After 20 minutes, close the globe valve. The air receiver will fill to "cut-out" pressure and the motor will stop. Before Each Start-Up: 1. Place On/Auto/Off lever to "Off". 2. Close the globe valve. 3. Attach hose and accessories. NOTE: A regulator MUST be installed when using accessories rated at less than 175 PSI. NOTE: The hose or accessory will require a quick connect plug if the air outlet is equipped with a quick connect socket. Risk of Bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer’s maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating. How to Start: 1. Turn the On/Auto/Off lever to "On/Auto" and allow tank pressure to build. Motor will stop when tank pressure reaches "cut-out" pressure. 2. When the tank pressure reaches "cut-out" pressure open the globe valve. IMPORTANT: When using regulator and other accessories refer to the manufacturers instructions.
